摘要
Penta- and hexa-substituted phenanthrenes and penta-substituted benzo[c]-phenanthrenes have been synthesized; these exhibit columnar phases and are electrically switchable when bearing chiral side chains. The liquid crystalline and electro-optical properties are described. A strong tri-state switching behaviour is observed with the phenanthrene derivatives. A helical phase structure, responsible for this switching behaviour, is proposed and the possible mechanism of the columnar phase switching process is discussed.
